Title: Hybrid polypeptides with enhanced pharmacokinetic properties
Inventor: BARNEY SHAWN
IPC: A61K38/08
Filed: 2000-07-10
Abstract: The present invention relates to enhancer peptide sequences originally derived from various retroviral envelope (gp41) protein sequences that enhance the pharmacokinetic properties of any core polypeptide to which they are linked.  The invention is based on the discovery that hybrid polypeptides comprising the enhancer peptide sequences linked to a core polypeptide possess enhanced pharmacokinetic properties such as increased half life. The invention further relates to methods for enhancing the pharmacokinetic properties of any core polypeptide through linkage of the enhancer peptide sequences to the core polypeptide. The core polypeptides to be used in the practice of the invention can include any pharmacologically useful peptide that can be used, for example, as a therapeutic or prophylactic reagent.

Abstract: L'invention concerne une électrode de référence à jonction fluide, qui présente des caractéristiques potentiométriques jamais obtenues auparavant, et comporte un élément de jonction liquide microfluidique se trouvant entre une solution électrolytique de référence et une solution d'échantillon. Cet élément de jonction liquide microfluidique possède un réseau de nanocanaux le recouvrant et reliant physiquement la solution électrolytique de référence à la solution d'échantillon, mais alors que la solution électrolytique s'écoule dans le réseau de nanocanaux et passe dans la solution d'échantillon à une vitesse linéaire, la solution d'échantillon ne pénètre quasiment pas dans le réseau de nanocanaux par le biais des mécanismes de diffusion, de migration, de convection ou d'autres mécanismes connus. Le nombre des nanocanaux est, de préférence, compris entre environ 100 et environ 10. De préférence également, ces nanocanaux sont sensiblement rectilignes et parallèles les uns aux autres. Selon l'invention, il s'agit d'un réseau de nanocanaux anisotrope. Ces nanocanaux sont également, de préférence, enrobés et leur largeur est, de préférence, uniforme et, quel que soit le nanocanal de l'ensemble du réseau, sa largeur est sensiblement égale à celle des autres nanocanaux. Ces largeurs sont, de préférence, supérieures à un nanomètre environ et inférieures à 500 nanomètres environ et, mieux encore, de 70 nanomètres. L'électrode, qui peut être fabriquée à partir de n'importe quel matériau approprié, peut l'être, de préférence, d'un polymère, mieux encore, d'un polymère du groupe constitué par le polycarbonate et les polyimides.

Abstract: Medical devices of synthetic rubber are prepared from cis-1,4-polyisoprene by dip molding without the use of sulfur-containing components. The devices have surprinsingly favorable tensile characteristics despite what is known in regard to synthetic cis-1,4-polyisoprene. In addition, the absence of both the proteins present in natural rubber and the sulfur components that are typically used in vulcanization of both natural rubber and cis-1,4-polyisoprene of the prior art renders the devices freely usable without causing the user to suffer Type I or Type IV allergic reactions that typically arise from contact with natural rubber.

Patent CA-2407579-A1 (CA)
Title: Calibration of a doppler velocimeter for stroke volume determination
Inventor: OSYPKA MARKUS J
IPC: A61B8/06
Filed: 2002-10-10
Abstract: Doppler Velocimetry is a widely used method for estimating stroke volume (SV). The accuracy and reliability of its measurement however, is dependant on a) the correct assessment of the aortic valve cross-sectional area (CSA), and b) the maximal systolic velocity integral (SVI). The invention avoids the conventional assessment of aortic valve CSA by using a calibration method: a reference stroke volume SV REF IS determined by a method different from Doppler velocimetry, e.g. by thoracic electrical bioimpedance (TEB), or thoracic electrical bioadmittance, measured via surface thorax electrodes (transthoracic approach) or via electrodes located directly on an esophageal catheter/probe (esophageal approach). In the latter case, if esophageal Doppler velocimetry is used, the same catheter can be used for the placement of the electrodes and for an ultrasound transducer. In the case of esophageal Doppler velocimetry, an additional benefit of the invention is that the Doppler catheter/probe does not need to be aimed precisely at the site of maximum flow amplitude, as long as a stable catheter / probe location is maintained within the esophagus.

Title: Burst qam downhole telemetry system
Inventor: TRAINOR WILLIAM
IPC: E21B47/12
Filed: 2001-06-22
Abstract: A downhole telemetry system that transmits a burst-QAM uplink signal to the surface of the well is disclosed. In a preferred embodiment, the well includes composite tubing having circumferentially-spaced electrical conductors helically wound within the walls of the tubing. A downhole instrument coupled to a pair of adjacent conductors transmits a burst-QAM uplink signal to a surface system similarly coupled to the pair of adjacent conductors. The burst-QAM signal, preferably comprises a series of data frames (602) carrying telemetry data. Each data frame is preferably preceded by a quiet interval (604) (when no signal is present), a timing synchronization sequence, and a training sequence (606, 608). The timing synchronization sequence is designed for easy timing recovery at the surface, and the training sequence is designed to aid the adaptation of the equalizer. The data frame itself preferably includes a synchronization field, a data count, and a checksum in addition to the data. Direct digital synthesis is preferably employed to modulate the uplink signal.

Title: Aggregate dilatometer device and methods of testing
Inventor: ZOLLINGER DAN G
IPC: G01N33/38
Filed: 2001-06-20
Abstract: Methods and devices for improved measurement of the thermal expansion and/or chemical reactivity of aggregates used in concrete and for similar substances.  Aggregate is placed into the chamber of a metallic container having an enlarged opening. The aggregate is placed in a water bath, and a tightly sealable lid is placed onto the container. The lid carries a linear variable differential transducer (LVDT). A thermocouple for sensing temperature is also retourned within the lid so that a sensor on the thermocouple contacts the water bath when the lid is secured onto the container. The LVDT is operationally interconnected with a storage or recording device. In a preferred construction the lid retains a tower member having a float that is freely moveably mounted upon a guide rod. Movement of the float is indicative of a volumetric change in the aggregate and water. In operation, the dilatometer device is used to determine the information relating to the amount of expansion or contraction of the aggregate in response to thermal changes.  In addition, the devices and methods of the present invention are useful for determining the degree of reactivity of the aggregate. The degree of volumetric change for the aggregate alone may be determined using equations that isolate and remove the expansion quotient of the water.
